How to do it...

To do this, perform the following steps:

1. Run the following lines of code in the REPL:

>>> from adafruit_circuitplayground.express import cpx
>>> RGB = dict(black=0x000000, blue=0x0000FF, green=0x00FF00, 
... cyan=0x00FFFF,
... red=0xFF0000, magenta=0xFF00FF, yellow=0xFFFF00, 
... white=0xFFFFFF)
>>> cpx.pixels[0] = RGB['red']

1. You should see the first NeoPixel turn red.
2. Use the following code to set the first eight pixels to one of the named colors in alphabetical order:

>>> for i, name in enumerate(sorted(RGB)):
...     cpx.pixels[i] = RGB[name]
